db2_conn_errormsg

Descrição

stringdb2_conn_errormsg
([ resource$connection
] )

db2_conn_errormsg() returns an error message and SQLCODE
value representing the reason the last database connection attempt failed.
As db2_connect() returns FALSE in the event of a failed
connection attempt, do not pass any parameters to
db2_conn_errormsg() to retrieve the associated error
message and SQLCODE value.

If, however, the connection was successful but becomes invalid over time,
you can pass the connection parameter to retrieve
the associated error message and SQLCODE value for a specific connection.

Parâmetros

connection

A connection resource associated with a connection that initially
succeeded, but which over time became invalid.

Valor Retornado

Returns a string containing the error message and SQLCODE value resulting
from a failed connection attempt. If there is no error associated with the last
connection attempt, db2_conn_errormsg() returns an empty
string.

Exemplos

Exemplo #1 Retrieving the error message returned by a failed connection attempt

The following example demonstrates how to return an error message and
SQLCODE value after deliberately passing invalid parameters to
db2_connect().

User Contributed Notes 1 note

It appears that if you specify an invalid ibm_db2.instance_name in your php.ini file, your cataloged db2_connect() will fail with a returned value of false and when you use db2_conn_error() or db2_conn_errormsg() to check on the reason, those functions will return an empty string.
